INSUVLTOR FOR FIBROUS MATERIAL..

SPECIFICATION forming part of Letters Patent N0. 774,548, dated November8, 1904.

Application filed February 16, 1904x Serial No. 193,909. (No model.)

T0 (all whom, t may con/cern:

Be it known that I, RAYMAND ANDLAUEE,

a citizen of the United States, residing at Kan- The object of theinvention is to preventV the decay of fibrous supports-such as posts,door-sills, or like perishable material--both above and below thesurface of the ground, and contribute to the tensile strength of thepost.

The invention consists in the novel construction and combination ofparts, such as will be first fully described, and specifically pointedout in the claims.

In the drawings, Figure 1 is a view of the invention applied to the endof a post beneath the surface of the ground. Fig. 2 is an enlarged viewof the lower end portion of the post, showing the auxiliary jacketpartially broken, the strips between the jacket and the post, and theartificial-stone veneer or covering. Fig. 3 isatransverse sectional viewtaken on the line m of Fig. 2. Fig. 4 is a view of a driven post incasedin an artiicial covering and with a corrugated wire jacket, a portion ofthe covering and jacket being broken away. Fig. 5 is a detail view ofone end of the post as seen in Fig. 4, showing the portion of the jacketextending over the end, the cement covering'being partially removed.Fig. is'view in perspective showing the invention applied to a squarepost, a portion of the covering and jacket being broken away. Fig. 7 isa View in perspective showing a modification of the means for retainingthe articial stone upon the post.

Similar'letters of reference indicate corre- `sponding parts in all thegures of the drawings.

Referring to the drawings, A represents a post or pole which, as shown,is circular in cross-section.

B represents the jacket, which extends around the lower end c of thepost and con- `centric with the longitudinal surface and the inner sideof the jacket. The jacket B consists of a woven wire, the meshes beingcoarse to aord passing of the covering when applied in asoft or plasticcondition. The jacket 5 5 extends from a position at its lower endopposite the lower extremity of the post upwardly the requisite distanceto extend above the surface of the ground. Between the inner side of thejacket and the surface of the 6o post areVY the series of verticalstrips b', arranged at short distances apart in the direction of thecircumference of the post and corresponding to the height of the jacketand secured to the post by nails or screwsZ. 6 5

C represents the artificial-stone covering, consisting of cement, whichis applied when in a soft condition and forced through the meshes of thejacket B into the space I) and filling said space, the cement beingapplied in alarge 7o quantity on the outer surface of the jacket andalso to the extreme lower end of the post and forming a solid base c,and at the upper end of the jacket the cement is extended considerablyabove it and to the surface of the post in an inwardly and upwardlyinclined direction, thus forming a diverting-surface to water, which maybe conducted downwardly on the post. Thus it will vbe seen that thejacket B, which is secured to the strips I) in 8o any suitable manner,isfembodied in the cement, and the post is insulated from moisture andthe decaying influences'of the earth, and particularly at the surface ofthe ground, where repeated action of heat and moisture 8 5 and frost isdestructive to the post.

In Fig. 4 vI have shown the jacket extended upwardly the full height ofthe post, so as to inclose the post. In this construction the strips maybe dispensed with and the woven-wire material forming the jacketcorrugated or bent inwardly at intervals, the corrugated meshes ccontacting with the surface of the post. The upper and lower ends of thewoven-wire jacket are bent downwardly and inwardly above and belowtherespective ends of the post, as seen in Fig. 5, the cement in aplastic state passing through the meshes and to the surface of the post.The cement covering is also applied to the outer surface of the jacketin suitable thickness to conform to the contour of the post, theperforations forming clench-keys for the cement. In this manner the postis given the utility of a stone post and may be employed advantageouslyto support barbed-wire fences, grooves e2 being made in the outersurface of the cement to support the wire, which may be wrapped aroundor otherwise connected with the post, with the jacket forming an envelopand embedded in the artificial stone, the corrugated woven wire beingemployed as in Figs. 4L and 5. The square post Gr, as shown in Fig. 6,may be employed instead of the round post, asin Fig. 4, with advantagefor various other uses, the cement covering adapting its useunderground. The square post G is provided with a perfor-ate jacketembedded in the cement covering, which is the same as the jacket in Fig.5, the corrugated-wire mesh being rectangular in Fig. 6. Y

Various cements may be employed, such as known as bituminous, with greatefiiciency and durability.

I have shown in Fig. 7 an alternate form of the strips to that shown at7) in Fig. l, the construction of which may be in grooving the post ormaking dovetail-shaped strips f, which form a clench-key for the cement,and connecting the strips with the post. In either manner the cement maybe applied to the grooves in lieu of the jacket B and anartificial-stone covering' securely held to the surface of the post. Thejacket B not only gives strength to the cement covering, but aordsresistance to sharp blows or heavy weights and maybe Varied inconstruction and of suitable perforated sheet material. The jacket maybe used in sectional parts for exposed surfaces of fibrous material.

Such other modifications may be employed as are in the scope of theinvention.

Having fully described my invention, what I now claim as new, and desireto secure by Letters Patent, is

1. An insulator for posts, &c., comprising a cement covering, aperforate jacket embedded therein, and suitable supporting devicestherefor, embedded in the cement between the jacket and the post.

2. In insulated structures, the combination with the fibrous member tobe insulated, of

strips upon the surface, a perforated jacket extending around thestrips, and a cement covering keyed to the jacket and also the saidstrips.

3. In insulated structures, the combination with the fibrous member tobe insulated, of strips upon the surface, a perforate jacket havingportions extending over the ends of the fibrous member and spacesbetween the jacket and said member, said jacket being secured to saidmember and a covering of cement keyed to the jacket and also saidstrips.
